In the leagues I run that have inexperienced and/or casual team owners, I always use the standard 5×5 roto categories because I feel that it would give me and the other experienced players an advantage. I know that the casual players in my leagues are using the rankings provided by the website on which we’re drafting or some other set of rankings from a major industry source. And almost all of those rankings are based on standard categories. If I replaced, for example, home runs with slugging percentage, I would be able to identify the players whose valuation or ranking would change with the different category. But the noobs would be using rankings made with home runs in mind.
I polled my Twitter followers to find out the most common uses of non-standard categories so that I could determine the players whose valuation/ranking changed the most when non-standard categories are used. The most common answers were OBP replacing batting average (which I covered here), slugging percentage replacing home runs, and OPS being added as a sixth category to the standard five hitter categories. Sorry if your league has a different non-traditional format.
Below are charts showing the biggest changes in SLG and OPS leagues. For an explanation of the methodology used, check out the OBP piece I just linked to. And if you’d like to see how all 242 hitters that I have projected are affected by SLG replacing HR or OPS being a sixth category, you can find the SLG list here and the OPS list here.
First up, guys who get a bump when slugging percentage replaces home runs.

Miguel Cabrera and Paul Goldschmidt are even more valuable in slugging percentage leagues, and they close the gap between them and Trout in auction leagues. Joey Votto shows up on this list just as he did in my OBP post. He’s obviously excellent, but the standard categories aren’t the best measure of his excellence.
Unsurprisingly, we see a few young first basemen here who haven’t reached the ‘power potential’ some thought they might. But really they just haven’t put up big home run totals. Freddie Freeman and Eric Hosmer may never settle in as 30+ HR regulars or even 25-30 HR regulars, but if you play in a slugging percentage league, their power plays. And Brandon Belt gets the biggest boost by switching to SLG. It’s possible his ballpark has something to do with it, but he’s very much in the Freeman/Homser mold. The only non-1B/DH player on this list is Yadier Molina who was 4th in the league in doubles last year.
Now the guys who you would prefer in a home run league. Read the rest of this entry »
